查询词典 regurgitation

Methods Using FC and conventional Doppler echocardiography methods,the effective regurgitant orifice area was calculated in 48 patients with isolated aortic regurgitation and a flat proximal flow convergence angle.

选择近端血流会聚角呈水平型的单纯性主动脉瓣反流患者 48例，分别应用血流会聚法和常规多普勒超声法测量有效反流口面积。

In the current study it is difficult to be certain that the decreased aortic distensibility in aortic dissection were due to structural changes of the aortic wall, or simply reflected dilated aortic dimension and aortic valve regurgitation. Further study is necessary to elucidate the underlying mechanisms for this abnormalities.

本研究用无创的超声技术证明主动脉夹层之升主动脉扩张性明显降低，这对主动脉夹层病因学的进一步深入研究无疑具有重要意义；但其降低是由于血管本身结构异常所致还是继发于血管内径的扩张尚有待进一步深入研究。

METHODS Left ventricular ejective fraction, regurgitant velocity and regurgitant direction were examined by color Doppler echocardiography in 151 patients with medium mitral regurgitation. The results of LVEF, regurgitant velocity and regurgitanting gradient were compared between patients with and without murmur grope.

随机选择151例经超声心动图检查，显示有中度及中度以上二尖瓣返流的患者，根据彩色多普勒血流显像分别测定LVEF、返流速度等超声参数，比较其在杂音组及无杂音组间统计学差异，分析其对听诊的可能影响。

Patients treated with ergot derivatives who had grade 3 to 4 regurgitation of any valve had received a significantly higher mean cumulative dose of pergolide or cabergoline than had patients with lower grades.

在服用麦角洐生物进行治疗的患者中，发生任何瓣膜3到4级返流的患者服用培高利特或卡麦角林的平均累积剂量显著高于瓣膜返流级别较低的患者。

Patients treated with ergot deriaties who had grade 3 to 4 regurgitation of any ale had receied a significantly higher mean cumulatie dose of pergolide or cabergoline than had patients with lower grades.

在服用麦角洐生物进行治疗的患者中，发生任何瓣膜3到4级返流的患者服用培高利特或卡麦角林的平均累积剂量显著高于瓣膜返流级别较低的患者。

Cardiac murmur can be easily heard in the patients with normal cardiac function, fast regurgitant velocity, thin chest wall and excursive regurgitation jets.

心功能低下、返流速度缓慢、胸壁厚、血流方向居中者不易闻及二尖瓣收缩期返流性杂音。

Objective To investigate the mechanism of functional mitral regurgitation.

目的 探讨功能性二尖瓣返流的机制。

Mitral regurgitation is one of the most serious heart diseases.

It has many applications, but this review focuses only on itsuse in the intraoperative evaluation of mitral regurgitation.

它有广泛的运用，但本综述只集中于其在对二尖瓣返流的术中评价中的应用。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.
